What's the difference?
Jeep Australia's first plug-in hybrid, the Grand Cherokee 4xe, has arrived at a time when the company’s sales figures need a decent shot in the arm.
Though it’s seemingly spearheading a large and extra-large SUV hybrid push into the Aussie market, with the likes of a Toyota LandCruiser 300 Series hybrid on its way, the marque’s debut PHEV is only available here in the range-topping Summit Reserve spec, and only as a five-seater.
So, does the 4xe have enough of a jump on any large SUV hybrid rivals – including a rumoured but postponed Ford Everest hybrid – and is it enough to give the brand a much-needed boost?
Read on.
Toyota Australia has made a raft of changes to the current LandCruiser 300 Series line-up as part of the latest round of upgrades, but even though the third-from-top Sahara gets a $1119 price rise, it doesn’t receive any updates.
In an increasingly competitive 4WD wagon market – where some car-makers are offering more standard features and tech at lower prices – has the venerable LandCruiser lost its lustre?
Read on.
A wise man* once said "Being first can sometimes feel like being wrong" and perhaps that's how it is with the 4xe, but at least Jeep Australia is giving the large SUV hybrid realm a good ol' try.

The company's first plug-in hybrid, the Grand Cherokee 4xe, is not perfect by anyone's standards, however, it is a definite move in the right direction.
It's a quiet and refined drive, it retains the brand's renowned 4WD capability, and even its hefty price-tag likely won't dissuade Jeep loyalists from giving it a go.
The Sahara version of the LandCruiser 300 is an impressive large 4WD wagon: refined and comfortable on-road, and it adequately retains that renowned ’Cruiser capability off-road.
It's supremely comfortable seven-seater and has heaps of potential as a touring vehicle, but while there's plenty to like about the Sahara spec, the updated seven-seat GXL (up $2029, to $110,820 excluding on-road costs) offers a more appealing compromise between price and features, especially now that it has a cool box in the centre console, four-zone climate control (previously two), and eight-way power-adjustable driver’s seat (with lumbar support), among other additions.
The LandCruiser 300 Series in Sahara spec strikes a nice balance between practicality and prestige.
The Sahara's exterior has a distinctive LandCruiser appearance: chunky but modern-ish and ready to be fitted with Toyota genuine accessories or aftermarket gear.
The Sahara is 4980mm long (with a 2850mm wheelbase), 1980mm wide and 1955mm high. It has a listed kerb weight of 2620kg.
The Sahara’s exterior has that distinctive LandCruiser appearance, but modernised.
Otherwise, there are chrome exterior mirrors and door handles, and dynamic indicators front and rear that add to its overall quietly classy appearance.
The Silver Pearl premium paint on our test vehicle costs $675. Other paint choices include Glacier White, Ebony, Crystal Pearl, Graphite, Merlot Red, Eclipse Black and Dusty Bronze.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV retains the regular model’s level of functionality but adds a reasonably classy touch to everything.
All seats offer adequate comfort, support and room.
There are plenty of storage spaces, cupholders etc, and charging points - two USB-A and two USB-C plus a 12V socket in the front and two USB-A and two USB-C plus a 230V point in the back.
Controls are generally easy enough to locate and operate although some buttons are positioned in awkward places – including drive-mode buttons under the steering wheel – and it sometimes takes a few finger-stabs at the multimedia touchscreen to get to where you want to go in the operating system.
In terms of packability, the rear cargo area has a listed 1067 litres of space, and, with the second row folded and out of the way, that space opens up to 2004 litres.
There's a sense of familiarity in the 300’s cabin – it's a functional yet premium space – and it's an easy cabin in which to become instantly comfortable.
The driver gets a heated and power-adjustable steering wheel, and ventilated, heated and power-adjustable seat (with power lumbar adjustment), while the front passenger gets a ventilated, heated and power-adjustable seat.
All seats are leather-accented, comfortable and there are soft-touch surfaces throughout the interior.
The Sahara's 12.3-inch multimedia touchscreen is a main feature in the cabin and it's easy to use, now with wireless Apple CarPlay and Android Auto, and there's a wireless charging pad near the shifter. There are USB-A and USB-C charging points upfront.
The centre console houses a cool box and its lid can be opened from either side, so driver or passenger can access whatever is inside.
And – will wonders never cease? – the Sahara has a powered sunroof (aka moonroof).
There are the usual storage spaces, cupholders, receptacles in the doors for bottles, and myriad other spaces for the stuff that you carry every day.
Second-row seats are in a 40/20/40 split-folding configuration, and the third row is a power-folding arrangement that stows away forwards and flat.
The Sahara's cargo space, when all seven seats are in use, is a listed 175 litres (VDA) behind the third row, increasing to 1004 litres when the second and third row are stowed away.
The rear cargo area has a 220V/100W inverter and four tie-down points.
The five-seat Jeep Grand Cherokee Summit Reserve 4xe PHEV has a MSRP of $129,950 (excluding on-road costs).
Standard features include a 10.1-inch multimedia system (with Apple CarPlay and Android Auto), a 10.25-inch digital instrument cluster, 19-speaker audio system, quilted Palermo leather-trimmed seats, air suspension and 21-inch alloy wheels.
It also has a heated steering wheel, 12-way power-adjustable seats and four-way power lumbar adjustment with memory for driver and front passenger, driver and front passenger seat massage function and heated and ventilated seats (driver, front passenger and rear outboard passengers).
A Mode 2 charging cable is also included.
An 'Advanced Technology Group' pack is available as a $5500 option and that includes a head-up display, a 10.25-inch screen for the front passenger, wireless phone charger, and night vision camera.
Exterior paint options include 'Bright White', 'Diamond Black', 'Silver Zynith', 'Velvet Red', 'Baltic Grey', 'Rocky Mountain', 'Midnight Sky' and 'Hydro Blue'.
The seven-seat LandCruiser 300 Series Sahara has an RRP of $139,310 (excluding on-road costs), up from $138,191.
Our test vehicle had a few extras onboard, though, including optional paint (Silver Pearl for $675), an EBC module, (estimated $235 fitted), an on-road towing kit (estimated $285 fitted), a 12-pin trailer wiring kit (estimated $525 fitted), brake controller wiring kit (estimated $625 fitted), giving it a total of $141,655.
Otherwise, the features onboard a standard Sahara include a 12.3-inch touchscreen (with sat-nav, and wireless Apple CarPlay and Android Auto), a wireless phone charger, four-zone climate control, leather-accented trim, a head-up display, a heated steering wheel, heated and ventilated power-adjustable front seats (with three-position driver's seat memory), heated second-row seats (outboard), and power-folding third-row seats.
There is also cooled centre console storage, a 14-speaker JBL premium audio system and a dual-screen rear entertainment system.
You do get a lot for your cash but, geez, with this price tag, you'd be silly not to expect to.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has a 2.0-litre four-cylinder turbo-charged petrol engine, two electric motors (one on each axle) and a 17.3kWh battery.
Combined engine and electric outputs for power and torque are 280kW and 637Nm, respectively. The 4xe has it over any of its stablemates equipped with the 3.6-litre Pentastar V6 petrol engine because that yields 210kW and 344Nm.
The 4xe has an eight-speed automatic torque-converter transmission and regenerative braking.
Drive modes include 'Hybrid' (with combined engine and electric motor providing “maximum instant torque and impressive acceleration”, according to Jeep), 'Electric' (“zero emissions”) and 'eSave' (aims to save battery power).
There are a few options available when it comes time to charge the 4xe.
The 4xe vehicle has a Mode 2 charging cable so you can charge it at home in less than 10 hours, according to Jeep.
With a full charge, the 4xe has a claimed driving range, on electric charge alone, of 52km.
Jeep reckons a Mode 3 (wall box) single-phase electric vehicle charger will fully charge the 4xe in less than three hours.
If out and about and looking for a charge, a 4xe driver can use the onboard 'UConnect' system to locate an appropriate public charging station.
The Sahara has the 300 line-up’s 3.3-litre V6 twin-turbo diesel engine, producing 227kW at 4000rpm and 700Nm from 1600 to 2600rpm.
It has a 10-speed automatic transmission, high- and low-range 4WD, as well as a centre diff lock.
What it also has is a handy array of 4WD-focussed driver-assist tech onboard, which includes crawl control, downhill assist, hill-start assist, multi-terrain select, multi-terrain monitor with panoramic view, and active traction control (A-TRC).
It also has what’s called turn assist which, when activated through crawl control, helps to reduce the 300’s turning radius by braking the inside rear wheel – and while it initially seems like a bit of a novelty, this feature may come in very handy if you have to work your way through especially narrow and twisty bush tracks.
As mentioned, the 4xe has a listed electric-only driving range of 52km.
On our official test day, we drove just under 50km on a full electric charge and then the rest of the trip was courtesy of the good ol’ petrol engine.
Jeep's official figure for the combined cycle is just 3.2L/100km, but that's predicated on keeping the hybrid battery charged at all times. On fuel-only we recorded 11.6L/100km.
The 4xe has a 72-litre fuel tank (you need 95RON premium to fill it), so going by that on-test fuel-consumption figure, you could reasonably expect to get a driving range of about 620km out of a full tank.
Add an approximate electric range of about 50km on a full charge to that figure and you have a total estimated driving range of 670km.
Official fuel consumption is listed as 8.9L/100km on the combined cycle.
I recorded 12.4L/100km on this test, which is reasonable considering I did a solid half-day of low-range four-wheel driving, book-ended by 100km of highway driving.
The Sahara has an 80-litre main fuel tank and a 30L sub-tank (totalling 110-litre fuel capacity) so, going by my on-test fuel-use figure (12.4L/100km), you could expect a driving range from a full 110 litres of almost 890km.
We’re all time-poor, right? So, why should I take up your time and rattle on about the 4xe for a thousand words when I can get the essence of it across to you, the reader, in a few sentences? Call me, Mr Thoughtful.
This is generally a big, quiet and refined, easy-steering large SUV, but it feels bulky at times and tends to be quite fussy on irregular surfaces, exhibiting a jittery ride on even brief sections of light corrugations on dirt tracks.
The 4xe’s PHEV set-up is smooth and highly responsive on-road and you can switch between the aforementioned drive modes to suit the circumstance.
Driving range on electric only is listed as 52km. I only recorded a total distance of just under 50km, and it’s a very quiet and smooth drive while relying on electric power.
It regenerates power rather quickly down big hills and via braking, but we’d exhausted all electric charge by the time we’d reached our 4WD test track.
As expected, this Grand Cherokee tackled every off-road challenge without any strife.
The air suspension, set to full off-road height, is a bonus.
Our 4WD test track consists of difficult set-pieces, including one small steep rocky hill that I’ve seen heavily modified vehicles struggle to conquer and, to the Jeep’s credit, it climbed the incline, no sweat.
The 4xe’s efforts were only ever hampered by its 'all-season' Continental CrossContact tyres (275/45R21) which are much better suited to blacktop driving and the fact the 4xe costs upwards of $129,950 and I didn’t want to risk any damage to it.
The 4xe has a listed wading depth of 610mm but our test track was dry so I never had the chance to do any water crossings.
The Grand Cherokee has a solid enough rep as a towing vehicle but, take note, the 4xe is rated to tow 2722kg.
The Sahara is quiet and well-behaved on-road.
Steering is light and responsive and, with a 11.8m turning circle, this big 4WD feels nimble in the bush, even on tight tracks or pinched approaches to hills or creek crossings.
The V6 offers up plenty of power and torque, and that’s smoothly managed through the 10-speed auto.
Ride and handling are well sorted but, this being a LandCruiser, it’s soft and comfortable, rather than dynamic.
Its suspension – double wishbone, independent at the front and live axle and multi-links at the rear, with coils all-around – manages to soak up most imperfections in the road surface.
The 300 Series' brakes – ventilated discs all-around – brought the big Cruiser to a controlled stop during two emergency-braking scenarios.
The Sahara does miss out on some of the handy 4WD gear featured in the two higher grades (Sahara ZX and GR Sport), namely Toyota's sway-bar-disconnect equivalent electronic Kinetic Dynamic Suspension System (included onboard the GR Sport), front and rear differential locks (GR Sport), adaptive variable suspension (Sahara ZX and GR Sport) and a rear torque-sensing limited-slip differential (ZX).
But ultimately, unless you're really going all-out to break your Cruiser while 4WDing, then the Sahara has enough old-school and new mechanicals and driver-assist aids to get you through the majority of off-road challenges.
Put it this way: we managed all obstacles at our testing ground without any strife.
The V6 produces more than enough power and more torque – up 27kW and 50Nm over the V8 – and that power and torque is consistently delivered across a broad rev range.
The 10-speed auto is a clever match for this engine, making for a smooth pairing, never floundering through ratios in an attempt to find the sweet spot; it’s always pretty close to bang-on.
High- and low-range gearing are solid in the 300 Series, and the Cruiser has a 50:50 centre diff lock.
There’s also a comprehensive suite of driver-assist tech onboard aimed at making your off-roading escapades easier and safer.
The traction control system has been well calibrated and is quite seamless in its application.
The 300's multi-terrain select system includes driving modes such as Sand, Mud and Rock to suit the terrain you're on. These modes adjust various vehicle systems – including throttle control, engine output, and transmission response – to give you the best chance possible of tackling every off-road obstacle safely and in a controlled fashion.
Off-road measurements and angles are decent: ground clearance is 235mm, wading depth is 700mm, and approach, ramp-over and departure angles are 32, 21, and 25 degrees, respectively.
As well as its dialled-in off-road traction control and all of those driving modes, it has handy tech such as crawl control, which works like a low-speed cruise control.
Its tyres are the only real flaw in the 300 Series’ off-road set-up, as its standard Bridgestone Dueler all-terrains (265/65R18) are better suited to dry-track, light-duty 4WDing in good weather than taking on any hardcore 4WDing.
In terms of towing capacity, the 300 Series can legally tow a 750kg unbraked trailer, and the industry-standard of 3500kg braked for large 4WD wagons.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has the maximum five-star ANCAP safety rating from assessment this year.
Safety gear includes AEB with pedestrian detection, blind-spot monitoring with rear cross-traffic alert, adaptive cruise control, lane-keep assist, driver monitoring, traffic sign recognition, intersection collision assist, and a surround-view parking camera.
The Summit Reserve spec brings with it 'ParkSense' parallel and perpendicular park assist and (low-level autonomous) 'Active Driving Assist'.
It has eight airbags including front, side, and knee (for driver and front passenger), sides (for second-row passengers) and full curtain airbags.
All of the 300 Series line-up, except the GR Sport, have the maximum five-star ANCAP safety rating from testing in January 2022.
Safety gear includes 10 airbags, two ISOFIX anchor points, as well as AEB with pedestrian and daytime cyclist detection, active cruise control (all-speed), Lane Departure Alert (with brake to steer), Road Sign Assist (speed signs only), Trailer Sway Control and more.
Off-road driver-assist tech includes crawl control, downhill assist, hill-start assist, multi-terrain select, multi-terrain monitor with panoramic view, active traction control and that aforementioned turn assist.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has a five-year/100,000km warranty and a lifetime roadside assist service.
Servicing is set at 12-month/12,000km intervals and capped price servicing keeps what you pay for each appointment at $399 for the first five.
The LandCruiser 300 Sahara is covered by a five-year/unlimited-kilometre warranty, which is par for the course in the mainstream market. Owners may extend the engine and driveline warranty to seven years by adhering to service schedules.
Service intervals are scheduled for every six months or 10,000km, whichever comes first. Those timings are shorter than the more usual 12 months/15,000km.
Capped-price servicing applies to the first 10 services at a cost of $420 each (correct at time of writing).
